Abstract:
A method for disaggregating amyloid peptide aggregates the method comprising administering a tanshinone or a tanshinone derivatives to an amyloid peptide aggregate. The method may be useful for disaggregating amyloid peptide aggregates in a patient in need of such treatment, such as patients with Alzheimer's disease.
Abstract:
The present invention provides an isolated bacteria designated Paenibacillus alvei TS-15 for use as a biocontrol agent in the inhibition and/ or elimination of a human foodborne pathogen, e.g., S almonella , on a plant or plant organ, e.g., a tomato or tomato plant. TS-15 or mutants thereof may also be used in the control of plant pathogens.
Abstract:
The invention provides a medical image transfer method and system, wherein the source Picture Archiving and Communication System (PACS) side and the determination PACS side are respectively provided with a transfer client end and a transfer server; the transfer client end receives the medical image data from the source PACS according to the Digital Imaging and Communications in Medicine (DICOM) standard, sets the transfer server address as the destination address of the medical image data, compresses the medical image data, and sends the compressed medical image data to the Internet by way of broken-point continuous transfer when the network status of the Internet is monitored to satisfy the transfer requirements of medical image data; the transfer server receives via the Internet the medical image data, whose destination address is the address of the transfer server, decompresses the medical image data, and sends the decompressed image data by DICOM standard to the destination PACS.

Abstract:
The present invention relates to a method for manufacturing a diamond composite, comprising the steps of: a) mixing diamonds with additives, the mixture comprising at least 50 wt% and less than 95 wt% of diamonds and more than 5 wt% additives; b) forming a work piece from the mixture using a pressure of at least 100 Mpa; c) heating the formed work piece to at least 300°C for removing possible water and wholly or partially removing additives; d) heating the work piece and controlling the heating temperature and heatin time so that a certain desired amount of graphite is created by graphitization of diamonds, wherein the amount of graphite created by graphitization is 3-50 wt% of the amount of diamond; e) infiltrating silicon or silicon alloy into the work piece, the infiltration of silicon or silicon alloy being performed at a temperature below 1900°C and a pressure less than 50 bars; and f) heating the infiltrated work piece to form silicon carbide, or other carbides, (and silicides), thereby creating a final diamond composite.
Abstract:
The present invention relates to a method of manufacturing a diamond composite body comprising the steps of forming a porous body containing diamond particles and graphite and/or carbon, infiltrating silicon or silicon alloy into the body and heating the infiltrated body to form carbide by reaction between graphite and/or carbon and the infiltrated silicon or silicon alloy. According to the invention the method comprises the further steps of providing a surplus of silicon or silicon alloy in connection with the infiltration step so that a layer of silicon alloy will cover at least one outer surface of the composite body, and thereafter machining the at least one outer surface covered with silicon or silicon alloy. The invention also relates to a diamond composite body produced by the method.
Abstract:
A composition is disclosed which is capable of being used for detection, comprising a noble metal nanoparticle. The inventive compositions exhibit little interaction with serum proteins while exhibiting pH-dependent adsorption onto live cell membranes. The nanoparticles of the claimed invention are capable of interacting with cell membranes, which in turn permits the advantages of nanoparticle bio-imaging to be extended to many pH dependent biological processes such as targeting acidic tumor microenvironment.
Abstract:

Abstract:
The present invention provides nanoparticles having bright fluorescence, where the total number of photons emitted from a single nanoparticle upon excitation with an excitation wavelength of the nanoparticle is at least 107, and giant Raman enhancements, where Raman signal for a molecule near a single nanoparticle increases at least 107 times. The nanoparticles of the invention comprise a plurality of crystallites that are each about 0.6 nm to about 10 nm in size. The present invention also provides methods for making the nanoparticles, which include mixing a matrix material with a reactant capable of being thermally reduced to form the nanoparticle; forming a mixed solid phase; and thermally reducing the mixed solid phase to form the nanoparticle.
